[摘要] 進(jìn)行了某復(fù)雜體形超高層建筑順風(fēng)向、橫風(fēng)向及扭轉(zhuǎn)風(fēng)致振動(dòng)時(shí)程分析，用每層質(zhì)量集中于樓板并視之為剛片的高層建筑層間結(jié)構(gòu)模型代替精細(xì)有限元模型。計(jì)算結(jié)果顯示結(jié)構(gòu)位移響應(yīng)以l階模態(tài)響應(yīng)為主，該模型代替精確有限元模型能夠滿足工程計(jì)算需要；對(duì)于質(zhì)量中心和剛度中心重合的結(jié)構(gòu)，扭轉(zhuǎn)加速度響應(yīng)在合加速度響應(yīng)中占有的比例較小。

Abstract: Along-wind, across-wind and torsional wind-induced vibration analysis of the super high-rise building with particular shape is done. Simplified model in which quality of each story has been concentrated into floor that is treated as rigid slab is used to substitute for precise finite element model. Result turns out that displacement response of the structure is mostly focused on the first order frequency in frequency field. Torsional acceleration response only takes a small part in the composition of acceleration response on account of overlap of quality center and stiffness center.
Keywords: super high rise building; 3-D wind induced response; simplified story model
